The Complete Guide to Void Fillers - Keep Your Cargo Safe and Secure

Shipping goods? One of the biggest headaches is keeping everything stable during transit. Packages shift because of bumps, sudden stops, or rough handling, which can lead to damaged products. That’s where void fillers come in. These handy solutions fill empty spaces in containers, keeping shipments secure and reducing movement.


Whether you’re in logistics, retail, or e-commerce, knowing the right type of void filler can save you from product damage, returns, and unhappy customers. Let’s break down what you need to know to keep your shipments safe and sound.

Why Void Fillers Matter

Shipping is full of movement, and even well-packed items can shift due to:


  • Vibrations from trucks, ships, or airplanes

  • Braking and sudden acceleration

  • Gaps within pallets or boxes

  • Pressure from stacking lighter items

Without void fillers, you risk:


  • Damaged products:  Fragile items like electronics and glassware can break or get scratched.

  • More returns & replacements: Costing your business money and disappointing customers.

  • Unstable loads: Which can be dangerous, especially for large freight shipments.


The right void fillers help prevent these problems, keeping your shipments intact and secure.
